Illllil Patented June 24, 1930' UNITED- STATES IGNATZ GONYK, OF VIENNA,AUSTRIA LADLE FOR LOW-MELTING MATERIALS Application filed August 28,1928, Serial No. 301,594, and in Germany August 26, 1927.

My invention relates to improvements in ladies for low melting materialsand comprises a ladle proper with a detachable handle. In the ladleproper a heating chamber is formed by means of partition walls. Theheating device which is to be introduced into the heating chamber isarranged at the front end of the handle of the ladle so as to projectfrom the handle when the same is in the detached position, whereas thefeed device for the heating device is arranged within the handle.

The heating device may either consist in an electric heating coil orsome other source of heat such as a burner for liquid fuel or a gasburner. It is an essential feature of my invention, that the handle isdetachable so as to make the ladle applicable with any of the abovenamed or other suitable sources ofheat.

The accompanying drawing shows by way of example different embodimentsof the ladle and the handle according to my invention, Figs. 1-5illustrating the apparatus with an electric heating device.

a of parallelopipedic, elliptic or flat cylindric sha e and a roundedoff front portion 6 of beaE-like shape; this part is covered 'by a plated which, however, leaves open the kennel c. The main portion is providedwith two longitudinal partitions f closed at the front by a cross wall eenclosing the heating chamber 71.; this chamber is open towards thebottom and partly closed towards the top by a cover having a slot g. Therear wall of The ladle proper comprises a. main portion the ladlecarries a connecting plate 11 of heat 1nsulating material such asebonite .with asbestos washer or the like (Fig. 4) from which areprojecting two screws with flat heads which-are passed into circularenlarged por- 66 tions of longitudinal slots is at the front part of thehandle 1 and are pushed downward throughsaid longitudinal slots thehandle and the ladle being thus joined by shifting in a detachablemanner. For securing this 60 connection a sliding bolt 0 (Fig. 5) isrovided which is adapted to be projected fi om the front plane of handleI, by a knob m and engage a hole 11 of the connecting plate z. The topof the ladle may be covered by a plate 6 p which leaves open the slot 9of the heating chamber h and which carries tongues 1 extending below thecover d of art I) of the ladle 'when the cover is applie to the ladle bymeans of a handle g. y

In the embodiment shown in Fig. 1 the handle Z has a lon itudinal borefor receiving a cable a of an efiectric heating coil 2.. The I bottom,of the heating chamber is closed by an asbestos lined plate u passed inbelow the heatin coil. v In t e embodiment shown in Figs. 6 and 7 aheating device for liquid fuel, particularly methylated spirit, is used.

The handle I of the ladle surrounds the recei ver of the liquid fuel,said receiver being provided with an inlet fitting and screw 11 and aneedle valve w by means of which the feed pipe w. may be controlled,which pipe leads to thecarbureter y of U-shaped crosssection. Into thecarbureter y is fitted a wick zof asbestos or the like. The fuel maenter through a bore 1 into the channel 2 ormed by the carburetor wallswhere it is ignited in order to efiect the preheating of the carbureterwalls whereafter the fuel gases pass fzppugh holes 3 and are used forheating the For heating the ladle by means of gas the handle (Fig. 8) isprovided with a longitudinal bore for receiving a gas pipe 4. Said pipeis connected to a burner tube 5 with holes 6 through which'the' gasescapes feeding the The rear end of the gas pipe carries a cock? forcontrolling or shutting off the a gas and a nipple 8 for connecting aflexible tube 9 of small cross'section to the gas pipe whereas theconnection of said flexible tube to the ordinary main gas tube is madeby means of a reducing nipple 10.

For operation the ladle the solid material to be melted is brought intothe ladle, the heating device is started and the molten material pouredthrough the kennel c to the desired place of use.

With the device according to my invention it is possible to effectcontinuous melting of solid goods no matter which of the hereinbeforedescribed heating device may be used. I

If the embodiment of the handle for liquid fuel or gas is used theflames ma be so regulated that they will not burn t rough slot 9.

What I claim is:

1. A ladle for low melting materials comprising a ladle proper, a heatinchamber in said ladle, and a detachable han le carrying a heating devicefor the ladle.

2. A ladle for low melting materials comprising a ladle proper, aheating chamber in said ladle, a detachable handle, and a heating devicepartly arranged in the handle and part1 projecting therefrom 'into theheating chamber of the ladle.

3. A ladle for low melting materials comprising a ladle r0 er, a beaksha d front portion in said ad e, two longitu inal partitions and a crowwall in said ladle so arranged as to form a central heating chamher, adetachable handle, and a heating device arranged in the handle andpartly projecting therefrom into the heating chamber of the ladle.

4. A ladle for low melting materials comprising a ladle proper, acentral heating chamber in said ladle, a detachable handle, a heatingdevice arranged in the handle and part1 projectin therefrom into theheating cham r of the adle, and a connecting de vice between the ladleand the handle consisting of a plate on the rear wall of the ladle, flatheaded screws on said late adapted to engage slots in the front we. ofthe handle.

5. A ladle for low melting materials comprising a ladle proper, acentral heatirig chaber in said ladle, a detachable handle, a heatingdevice arranged in the handle a connecting device between the ladle andhandle, and a sliding bolt in the handle ada ted to project into a holein the plate of the adle to lock the connection.

In testimony that I claim the foregoing as my invention, I have si ed mname.

I NAT GONYK.
